The objective of this report is to provide the basis for the selection of this transition leak size for testing in the LLTR. This test, designated as Test A-4, is of particular interest because, of all the larger nonflame-jet-type-leaks, it has the longest dwell time in the vessel before the rupture disc blows, thus terminating the IHTS pressure rise. Its potential for generating secondary leaks is considered high. It is easy to postulate the generation of such a leak starting with small leak wastage and progressing into larger and larger leak sizes by self-wastage and adjacent tube wastage. On the other hand, it is not easy to postulate an instantaneous DEG failure in a properly designed and manufactured steam generator. All small leaks which are not terminated would appear to progress in stages which eventually pass through the transition size before they generate sufficient pressure to burst the rupture disc. For these reasons major emphasis is placed on the transition leak size.
